SPECIFICATION forming part of Letters Patent No. 492,924, dated March'7, 1893.

Application filed April 9, 1892. Serial No. 428,439. (No model.)

To all whom it may concern.-

Be it known that I, MORRIS LAOHMAN, a citizen of the United States,residing at London, England, have invented certain new and usefulImprovements in Rollers, Vheels, and

Similar Articles, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improvedconstruction of rollers, wheels and similar articles, the inventionrelatingparticularly to the construction of small rollers or wheels suchas are used for furniture casters and similar purposes, but beingapplicable also to larger rollers and wheels, and to pulleys and otherarticles of alike nature.

I form my improved roller or wheel in two parts or halves each of whichis stamped or pressed up from a single piece and forms one end and apart of the tread of the roller or wheel, these two parts being joinedtogether at the edges by soldering, brazing, welding or in any othersimilar manner to form the com plete article. In orderto strengthen theroller and to provide an extended bearing surface for the roller on itsspindle or shaft, the edges of the central spindle opening are turned toform flanges preferably extending inward- 1y, these flanges beingpreferably formed by the same stamping operation with the constructionof the rest of the half of the roller. The stamping may be effected byany suitable means, such as suitably shaped dies or plunger-s, andmachines of various forms may be used-for this purpose.

For a full understanding of my invention 1 have illustrated the same bytheaccompa- 4o nying drawings forming a part of this specification, inwhich Figure 1 shows in cross section the two parts of a roller of thepreferred construction before uniting. Fig. 2 is a cross section of 5the completed roller and Fig. 3 is an inner end view of one of theparts.

Referring to the drawings-a, a are the two parts or halves of theroller, each of which forms-an end and a portion of the tread of theroller, these parts being formed by stamping up single pieces of metalinto the form desired. These parts a may have any form desired'butpreferably are provided with inwardly extending flanges about thecentral spindle opening, these flanges being preferably formed with therest of the parts a, a. at a single stamping operation. The edges of thetwo parts a, a may be plain or formed in any suitable manner so as toaid in making the joint by which they are united, and the two parts maybe united by any suitable means as by soldering, brazing, welding orotherwise. I prefer, however, to form the two parts a, a with edgesreduced in thickness by spinning or otherwise, one from the outside andthe other from the inside, so that these reduced portions 2 overlap eachother and aid in forming the joint, and the edges are preferably joinedby solder and pressure.

What I claim is 7o 1. A roller or wheel formed of two pieces of metal,each stamped up to form an end and a portion of the tread of the rolleror wheel, and having their edges united, by soldering, brazing orwelding, substantially as described.

2. A roller or wheel formed of two pieces ofmetal, each stamped up toform an end and aportion of the tread of the roller or wheel, and aflange about the spindle open.- ing forming a bearing-for the spindle,and having their edges united by soldering, brazing or welding,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
